CAB LEI-SUSPENSION DEVICE.

Specification of Letters Patent.

Patented Nov. 5, 1907'.

Application filed October 3| 1906- Serial No. 337,220.

To all whom it may concern:

Be it known that I, MALCOLM CARY WILLIAMS, a citizen of the UnitedStates, and a resident of Kansas City, in the county of Jackson andState of Missouri, have invented a new and useful Improvement inCable-Suspension Devices, of which the following is a specification.

My invention relates to devices for suspending cables,-for example,telephone cables,-from spanwires, and the object of my invention is toproduce a simple and efiicient suspension device which may be attachedto and removed from span-wires without requiring the use oi specialtools. p

One embodiment of my invention is illustrated in the drawings whichaccompany and form a part of this specification, in which Figure l is aperspective view of my cable suspension device as employed in practice,and Fig. 2 is a perspective view of said 4suspension device turnedthrough an angle ofabout 180 degrees from the position shown in Fig. I.

In the figures A represents a span-wire of the usual type, which issuspended between two supporting poles.

B represents my cable suspension device, and C represents any suitablemeans, such as a loop of tarred rope, for supporting the cableD to thesuspension device B. v

As shown, my cable suspension device is formed of a single piece oiresilient preferably galvanized iron or steel wire bent at one end toform a loop, the two portions b and c of which are in the same plane,and the end portion a of which extends upwardly and is disposedangularly to said plane. The portion c is continued into an outwardlyextending portion d formed by bending the wire outward and backward soas to form a thumb-piece d extending substantially in a plane at rightangles to the plane of the portion b c. The thiunb-piece d is continuedinto the ring portion e, which as shown, has its plane substantially atright angles to the plane of the portion b c.

In order to attach the cable suspension device to the span-wire, theoperator grasps said device by the ring e and thumb-piece d and holdingthe same with the plane of the loop b c parallel to the axis of thespanwire, as shown at Af in Fig. 2, presses the device against thespan-wire, so that the latter is squeezed between the lower end f of theloop and the upper portion ofthe thumb-piece d, and after the span-wirehas been snapped under the above mentioned portion f, the device islowered and tilted to the left, so that the span-wire clears the upperend of the portion a, whereupon the operator turns the device at rightangles to its original position, so that the plane of the loop b c isnow at right angles to the axis of the span-wire, as shown at A in Fig.2. The cable suspension device now being locked upon the span-wire,cannot be removed therefrom bythe motions to which the cable D issubjected, but can only be removed by performing in reverse order theabove mentioned operations whereby the same was secured to thespan-wire.

It will thus be seen that I have provided a very simple and inexpensivedevice for suspending cables from span-wires, and that no special toolis required either for attaching the device to, or removing the samefrom, the span-wire, in contra-distinction to devices heretoforeemployed, in which the suspension device generally is provided with ahook which passes over the span-wire and which must be bent around thesame by means of pliers or other tools.

It will be understood that although the device herein described hasgiven good results in practice and is in fact -the preferred form of myinvention, nevertheless many modifications may be made therein withoutdeparting from the principle of my invention, and therefore I do notwish to limit myself to the exact form of apparatus herein disclosed,but

What I claim and desire to secure by Letters Patent is: i i

1. A cable suspension device consisting of a single piece of resilientwire provided at one end with a loop whereby said device may be attachedtoa span-wire, said loop having an uinwardly-extending; end portionangularly disposed to the plane thereol'and means for supporting a cablebeingl continued into an outwardly extending portion lying in a planesubstantially at right angles to the plane of said loop, and the lowerportion of said loop and said outwardly extending' portion forming anentrance to said loop -which is smaller than the diameter of thespan-wire to which said device is to be applied, whereby said device maybe snapped onto said span-wire and then turned at right angles theretofor lockingl the same to said span-wire, and means for supporting acable from said device.

ln testimony whereof, I have hereunto subscribed my name this 25th dayof Sept. 1906.

MALCOLM CARY WILLIAMS.
